Firstly if you have another power lead check that. If that gives the same then read on.

When it comes to laptop power supplies it's easier and more cost effective to replace them.

The parts inside are dangerous, packed in very close to each other and hard to fault find the entire fault. Half the time fixing one fault, you can miss another that is buried under other components.

Try and find an ex-government/ex-lease computer seller etc in your area. They will have another adaptor second hand, or even use things like eBay etc. Just be sure to get things from good sellers, and make sure they are in your country.

If you go back to HP (they own Compaq now) you will be charged an arm and a leg for a new charger.

How do I get my computer to recognized my new ac power adapter?


The computer doesn't need any drivers to recognize an AC Adapter. If you have purchased the correct AC Adapter for your laptop then it should just work when you plug it in. If it does not then my guess is either you have received a faulty AC Adapter or the DC Jack which you plug into in the back of the laptop is bad.
I am assuming your battery is dead and when you plug it in and turn it on nothing happens?
You can also try taking the battery out and try to power it on with the AC Adapter plugged in.

The Dell Latitude D610 takes a PA-10 or PA12 AC Adapter. It's 65W or 90W

For 90 watt Adapter the output voltage on your AC Adapter label should read 19.5V and 4.62A
At least that's what the Dell brand reads so it should be close to that.

I bot a hp mini laptop recently.. ws working well..bt sddnly it ws nt chrgng ystrday and showed cross sign over battery in control panel.. why is it nt chrgn and wht to do?


If the laptop is still working when it is plugged in , then the ac adapter is good and the battery is just bad. If the laptop will not work when it is plugged in then more than likely the ac adapter is bad.

My dell vostro 1000 laptop's display aint working. The screen remains black. Even the battery light doesnt glows. Only the power light comes on. Please help.


hi,
try these two things if both don't work you should call dell tech support

1) take out the battery and the ac adapter and then push and hold down the power button for 15 seconds, this releases flea power in the laptop and makes it work sometimes
if it didn't work

2) take out the battery and put in the AC adapter and try to start your laptop on AC adapter alone, if it starts that means either your battery or *********** board is bad, you can check if the battery is bad by replacing it with a new battery and if it works with new battery that means the old battery was bad but if it only works without battery with ac adapter and new battery also didn't work, that means motherboard is bad, Call dell tech support

If you think the info given by me was helpfull please do rate me
Regards

On the issue with th ebattery on the 1521 inspiron. Took battery out and plugged in still will not power up. Could it be the adapter as well?


On the ac adaptor, look for a green light that will turn on when you plug it into the wall outlet, if its on that means the ac adapter working. If you get a green light on the ac adapter but then the green light goes away when you plug it into the laptop then that means the laptop has a bad motherboard.

If you plug the ac adapter into a wall outlet and get no green light then that means the ac adapter is bad and you would need to get another one.

Ac adapter does not connect to battery


You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad

Dell inspiron 1501 work fine turn off last night now wont turn on


You mentioned trying a different battery, try a different AC adapter.

When plugging in the ac adapter to the wall, see if the POWER LED comes on on the adapter, then when you connect it to the computer, see if the LED stays on.

If the issue occurs with both AC adapters (No battery installed) then the motherboard has failed. If one ac adapter works but the other doesn't then the adapter is bad

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
